Matekasse hangs sporadically
Every now and then Matekasse does not respond to a client requests. Pi has to be rebooted to get it running again. The time to the next issue appearance is not constant. The number of requests per time also does not make the server hang. SSH login after the issue appearance is also not possible. So, it might be very well the case that the reason for the problem is in the underlying infrastructure.
To reproduce - observe the client not being able to refresh the page and not showing content (either open the Matekasse page from within the network or check the tablet in the kitchen on the fridge).
My modest attempts to find the source code of the server app running there have failed too (perhaps due to my limited knowledge of the infrastructure).
There also was an idea/intention to move the Matekasse service to VM. Not sure if the decision has already been made.
I would be happy to help observing and fixing the issue. I can also improve the client to prevent it from refreshing while scrolling down. Up on refresh the list of members will be re-populated and it is hard to find the item in the middle of the list that is jumping every 2-3sec. It is the subject for a separate ticket, though.
I look forward to your comments and thoughts on the issue.
